(Ci. SSL-39) p 4 Claims The .present invention relates Yto magnifyingglass attachments lwhich may be removably mounted upon electric lampreflector, and has for its principal object the provision ofa shieldwith a magnifying glass mounted therein, and which may be removablyattached tothe lamp reiie'ctor, and angularly adjusted thereon, for thepurpose of freeing the hands of the user, eliminating the necessity ofhandling the object examined by one hand and a magnifying glass by theother, permitting the user to have his both hands free to handle theobject while examining an object under the magnifying glass.

A still further object of the present invention is the provision of ashield within which a magnifying glass is mounted, and which is suitablyformed along one of its edges to removably engage a circumferential beadformed in electric lamp shades or reflectors in electric lamps of desktype, and wherein the lamp and the reflector are supported by a flexibletube whereby the position of the reflector may be adjusted.

With the above general objects in view and others that will appear asthe invention is better understood, the same consists in the novelconstruction, combination and arrangement of parts hereinafter morefully described, illustrated in the accompanying drawing and pointed outin the appended claims.

In the drawing forming a, part of this application and in which likedesignating characters refer to corresponding parts throughout theseveral Views;

Fig. l is a side elevational view of an electric lamp reflector with thepresent device attached thereto in an operative position;

Fig. 2 is an end elevational View of the electric lamp reflector withthe present device attached thereto, the latter being shown in a sideelevation;

Fig. 3 is a cross-sectional view on line 3-3 of Fig. 1; and

Fig. 4 is a cross-sectional view on line 4-4 of Fig. 1.

Referring in detail to the present drawing there is shown therein anelectric lamp shade or reflector I which is adapted to receive anelectric bulb (not shown), and which is attachable to a socket Il, whichin turn is carried by a flexible tube -I2 through which electric wiresextend and connect with the electric bulb terminals in socket Il.Reflector I0 is provided with an outwardly extending bead I3 integrallyformed with the body of the reflector and along its marginal edge.

The .present invention, intended to cooperate with the lamp reilectorI0, includes shield Iii, which may be of any desired shape or formation,and which, adjacent one of its edges isangular-l'y bent as at I5. Theedge of said shield' I4 adjacent bend I5 is slightly curved or flangedto affect downwardly turned lip Iii .for the purpose of engaging saidbead I3 outwardly thereof land from an upward direction, as is clearlyseen in Fig. 4.

Cooperating with shield I4 is a pair of oblong resilient plates I 'Ipivoted by one of their ends upon bolt I 8, provided with head I9 incontact with the outer face of shield I 4, and having shank 20 uponwhich plate Il is set for horizontal angular swinging movement, and heldin spaced position from shield I 4 and nut 2| by means of a pair ofinterposed washers 22. Said nut 2| remains in a threaded engagement withthe reduced outer end of said bolt I8, as is seen in Fig. 4.

From the hereinabove description it will be` readily seen that lip I5engages bead I3, and plates I1, bearing upon bead I3 from below, retainshield I4 in an attached, adjusted position, upon reflector Ill. Byangularly swinging plates I1, the same may be entirely disengaged fromrelector I il, thereby permitting removal of shield I 4 therefrom.

'Struck out from shield I4 and centrally thereof, is a cylindricalsocket 23, provided at its outer free end with an inwardly extendinghorizontal Ila-nge 24,which remains in a perpendicular position withrespect to socket 23. Inserted within said cylindrical socket 23, andsupported at its margin by Ilange 24 is magnifying glass 25.

Insertable within said socket 23 and frictionally held therewithin is aretaining ring 26, having an inwardly extending flange 2l., which,cooperating with flange 24, and bearing against the opposite face ofmagnifying glass 25 retains the same within socket 23 and in a rigidrelation therewith.

From the hereinabove description it will be apparent that shield I4 maybe angularly adjusted upon reector l 0. It will also be seen that theobject to be observed under the magnifying glass is placed in backthereof and below reflector Ii), and illuminated by the light from theelectric bulb in the reflector. The observers both hands may be used forhandling the object under observation.

While there is described herein a preferred embodiment of the presentinvention, it is nevertheless to be understood that minor changes may bemade therein without departing from the spirit and scope of theinvention asV claimed.

What I claim as new is:

1. A magnifying glass fixture attachable to a lamp reflector having abead, comprising a magnifying glass mounting shield, a downwardlyprojecting lip along the marginal edge of said shield for superimposingsaid bead, and a plurality of resilient plates in pivotal engagementwith said shield for engaging said bead at points substantiallydiametrically opposite from those at which said lip engages said bead,said plates being resilient in a plane substantially normal to the planeof the pivotal movement of said plates.

2. As an article of manufacture a magnifying glass fixture comprising aplate, a socket integrally formed with said plate for receiving amagnifyl ing glass therewithin, a lip angularly depending from saidplate, and a plurality of resilient plates in pivotal engagement withsaid plate, normally lin transverse relation with said lip, and adaptedto be angularly swung upon their pivots away from said lip, saidswinging movement of said plates being in a plane disposed at an angleto thev resilient movement of said plates.

3. In combination with a lamp reflector of the type having asubstantially annular body portion and a bead along its marginal edge, amagnifying glass mounting shield, one edge of said shield being ofannular formation corresponding to the contour of the body portion ofsaid reflector, an angularly depending lip from said shield and alongsaid edge, said lip being adapted to superimpose and engage said beadwhen said annular edge of said shield is in contact With the bodyportion of said reflector, and means upon said shield for engaging saidbead at points substantially diametrically opposite from those at whichsaid lip engages the same.

4. In combination with a lamp reflector of the type having asubstantially annular body portion and a bead along its marginal edge, amagnifying glass mounting shield, one edge of said shield being ofannular formation corresponding to the contour of the body portion ofsaid reiiector, an angularly depending lip from said shield and alongsaid edge, said lip being adapted to superimpose and engage said beadwhen said annular edge of said shield is in contact with' the bodyportion of said rei-lector, and a plurality of resilient plates inpivotal engagement with said shield for engaging said bead at pointssubstantially diametrically opposite from those at which l said lipengages the same.
